Paucity of Hematozoa in Colombian Birds

Sixty-four birds of 43 species were caught at six localities in Colombia during the dry season in March 1998 and investigated for hematozoa by microscopic examination of stained blood films. Haemoproteus coatneyi, Plasmodium vaughani, Leucocytozoon sp., and microfilariae were identified. The overall prevalence of infection was 8%. Prevalences of infection for Haemoproteus spp., Plasmodium spp., Leucocytozoon spp., and microfilariae were 3%, 2%, 2%, and 3%, respectively. All hemosporidian infections encountered were of low intensity (< 1% of infected erythrocytes). The low prevalences and intensities of hemosporidian parasites in this study are in accord with other records from the Neotropics.
